Mexico is urgently revising its trade policies and supply chain strategies amid fears that its role in the U.S.-Mexico-Canada Agreement (USMCA) could be at risk. Rising allegations that Mexico serves as a conduit

Mexico has been taking a bashing for allegedly serving as a conduit for Chinese parts and products into North America.

Canada wants Mexico to stay in a continental trade pact despite concerns about China possibly using it as a back door to flood the North American market, a source directly familiar with the matter said on Wednesday.

Mexico's president has acknowledged that Canada is concerned about reports of a Chinese company's auto plant in Mexico, but she says it does not exist.

Meeting between the countries' leaders comes amid calls in Canada for that nation to enter a bilateral trade deal with the United States.

Trudeau said he would prefer the North American free trade agreement to remain in place, but that Ottawa was 'leaving all doors open' to secure Canadian interests.
